Claims. (Cl. 2042) The present invention relates to window constructionand has for its main object the provision of means whereby two windowsashes may remain upon the same providing ventilation, and whereby thetwo window sashes may be brought to a horizontal position to permitaccess to the outer faces of the Window panes for cleaning or washingthe same.

Still another object of the present invention is the provision of asuitable mechanism whereby one of the window. sashes may be bodilyshifted inwardly of the dwelling and brought within a plane removed fromthe plane of the other window sash, and whereby the first of said windowsashes may be shifted in a vertical direction upon the plane which isremoved from the plane of the other window sash.

Still another object of the present invention is the provision of meanswhereby a window sash, when angularly shifted out of a window opening,may be maintained in its angular adjusted position;

A still further object of the present invention is the I provision ofnovel means for guiding the upright shifting movement of a window sashbodily within a window opening, irrespective as to whether the windowsash has been angularly shifted within a dwelling or whether the same isin its normal closed position within a window opening.

A still further object of the present invention is to generally improvea window construction, including a window frame and a window sash of thetype capable of angular adjustment within the window frame and capableof upright shifting movement within the window frame either during itsnormal closed position or its angular adjusted position.

With the above general objects in view and others that will appear asthe invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts hereinafter morefully described, illustrated in the accompanying drawings and pointedout in the appended claims.

Fig. 8 is a similar view as that shown in Fig. 7 of the lower windowsash, illustrating the angular position of the lower window sash withthe mechanism for supporting said window sash in that position;

Fig. 9 is a fragmentary face elevational view of the lower window sashwith the mechanism whereby the said window sash may be shifted andsupported in its positions shown in Figs. 7. and 8, the View having beentaken substantially upon a plane indicated by line 9-9 of Fig. 7; and

Fig. 10 is a perspective view of a portion of the mechanism whereby thelower window sash may be shifted to the various positions aboveindicated and illustrated in Figs. 4, 7 and 8, and whereby the same maybe maintained in those positions.

Referring in detail to the present drawings there is shown therein awindow frame which includes vertical frame side members 11, lowerhorizontal frame member 12 and upper horizontal frame member 13. Innerwindow sill 14 is rigidly supported upon said lower horito the innerfaces of said vertical frame side members 11 are molding strips 19,which are in a spaced relation with the oppositely disposed inner facesof said frame bars 17. Afiixed to the inner face of each of said moldingstrips 19 is weather strip 20, including an inwardly directed extension21.

Fitted within the window frame as hereinabove defined is a lower windowsash, which includes a lower horizontal sash bar 22, upper horizontalsash bar 23 and a pair of vertical sash bars 24, said bars beingarranged in a frame for maintaining therewithin window pane 25.

The upper window sash includesa lower horizontal sash bar 26, anupperhorizontal sash bar 27 and a pair of vertical sash bars 28, said barsbeing arranged in a frame for maintaining therewithin window pane 29.

The upper horizontal bar 23 of the lower sash and the lower horizontalbar 26 of the upper sash are suitably molded to define scarf joint 30,so formed however that when the two sashes are in a mutually closedrelation within the window frame, as seen in Fig. 2, the upper windowsash cannot be moved either vertically or angularly until the lower sashby its upper portion has f Felt weather-strip '31, 'is aflixed to theinwardly dis:

P951114; c of mq'ld ri 1 d s n rp se therebctween the vertical sash bars'24 and 28' of the two windowsashes, as, best seen in Figs. 3 and 6 forpreventing dust andhw'ind from entering'the dwelling'when the two sashesremain in a closed position within the window frame. t

- ferried-upon the inner face of each vertical sash bar 24 and-'28of-the two window sashesis molding strip plate 32, which by its innerfree edge, which defines lip 33', overl-aps-and-engages extension 21 ofsaid weather strip 20, as is best seen in' Fig. 6-. Thus, 'when the twowindow sashes are -in a closedposition within the window frame,extensional-and lip '33- are in a mutually contacting relation forproviding a seahfor-preventing dust or wind from entering a dwelling; l

' Itis further observed that when-the two sashes are in a mutualverticala-linement, as seen in 'Fig, 2; the'lower horizontal bar 22 of the lowerwindow sash remains in eont-act wi th the outer edg elof the windowsill'14, while the upper horizontalf'bar 27 of the upper 'sash remainswithin'recess-lo of board 15. I j j Each of the vertical sash, bars 24and 28 of the .two window-sashes remain spaced from each vertical frameside member 1 1, asbest seen in Fig. 6, and in conjunction withframebars1'7- and molding strips 19 define oblong vertical jhousings 34;, oneadjacent each of said" vertical framcside-mernbers 11, extending alongthe entire height of the window frame, as best seen in Figs. 3 and 6.;

Positioned within each housing 34' and rigidly secured by their ends tothe lower and upper horizontal frame members-Hand 13, is a pair of rods'35. With relation to-theinside of the dwelling a pair of opposed rods35 which are farthest removed from the dwelling, or. more specificallythose which are nearest to frame bars 17, will be hereinafter referredto as outerrods 35, while a pair of opposed rods -35'which are nearestto the dwelling, or more specifically those which are adjacent moldingstrips 19, 'will be hereinafter referred toast-he inner rods 35. Afiixedto eachof the side edges of the vertical sash bars 28 oftheupper windowsash, by'means of a plurality of screws 36, andadjacent the lower' endthereof, is plate '37-, Positionedupon-cachet said 'outer rods 35yfor'upright sliding thereonis a-lower sleeve 38 and an upper sleeve 39;Extending from the-'l-'ower end of the lower sleeve 3.8,in the directionof each of said vertical sash bars 28, is'pin 40 whichenters an apertureprovided in the lower end of each plate 37, and-thereby forms-a pivotfor the lower most end ofthe upper window sash, uponWhichthe-latter mayangularly swing'as is seen in Fig. 4. As an alternative construction ofthe said pivot, shown in Fig. 5, rod

'41 is made to extend-through the entire length of the lower 'horizontalsash bar 26 and through the-two plates 37, and enter, by its ends anenlargement 42- made atthe lower .endof each sleeve 38, and thereby forma pivot upon which the upper window sash-may angularly. swing inwardly fthe. dwelling, as shown .in Big. 4. T

Ooactingwith'each' side of the upper window sash is arm:,43, which byits lower end is pivotal'ly .affixed, .as at 44, to plate 37:, at apoint substantially centrally ofthe latter, and by itsoupper endzispivotallysconnected, as at 45,10 sleeve .39., adjacent the lower endthereof.

Assuming that the lower window :sash. :is angularly shifted out'of thewindow .openihgand otherwise out. of thepa th of: the upper. windowsash, the conditions which willbe. later apparent, the. upper: windowsash; is capable fiangularly shifting :Within the dwellingfrom thewindow open n f n of assuming various angular positions; fromalmostventical position. to. the ;horizontal-position,-; the latterbestshownin: Bi ;:4.. When in thatilatterpo t the outer face of the windowpane 29 will become exposed withinthe dwelling thereby permitting readyaccess thereto for the purpose of washing the same. One of theintermediate positions of the upper window sash between vertical andhorizontal is indicated by dotted lines in Fig. 4. When in one of saidintermediate positions the opening of the Window will provideventilation.

Regardless as to what extent the upper window sash' is angularly shiftedfromw-ithin the window opening the former moves upon its pivot 40 or 41."When the upper window sash remainsfin'a horizontal position arm 43shifts to an angular position both with relation to the upper sash andto the upper sleeve 39 as is seen in Fig. 4. Since said upper sleeve 39is capable of shifting :upon each of outer rods 35 to or away from thelower sleeve 38, the two sleeves remain in a spaced mutual relation, asis seen in Fig. 5, with arm 43 remaining in a vertical position when theupper window sash is-within the window opening. When however the upperwindow sash'has beenangu'larly shifted to the horiz n 'po ion, s o in Fs-v ia-upper sleevej3'9 by its lower end comes incontac't with the npperend of lower sleeve .3 8, and the latteracts as a stop for preventingfarther angular shifting of the. upper window sash'beyond' thehorizontal plane.

When thelower window sash has been angularly shifted it is possible forthe .upper window sash to shift downwardl y and within the confines ofthe lower. portion ofthe window opening, the outer rods 35 guidingsleeves '38 and 39 in' their shifting movement.

Referring to the mechanismfor angularly shiftingi the lower window sashwithin. the window openinggpositions best shown in Figs. 4'and8, as wellas for'bodily moving the lower window sash away from the planeofithe'upper window sash, position best shown inFig 7; thesame in:cludes a pair of lower sleeves 46. and a pair of upper sleeves47'positioned' for upright sliding movementmpon V inner rods 35. V

An 'L-shaped' member, generally indicated by 48 in Fig;

7 ,1 0, fitted upon each of the two lower edge corners oftlie y d sthehor o ta lower sash, includ'es side plate 49, afiixed by a'plurality ofscrews 50 to each side edge of vertical sash bars 24., and bottom plate51 afiixed to each end; ofthe'loweredge of the lower horizontal sash bar2 2 by means of screws which pass through apertures 52. The lower end ofplate 49"has an extension 53. directed toward a dwelling, with an xar=cuate recess 54, opening upon the outer edge of said plate 49 andentering saidextension 53.

The ends of the lower; horizontal sash bar 22' are-filed away from thecontinuing side edges of the vertical sash bars24, for defining, 1nconjunction with the lower end' of each plate 49 a recess 55, foraccommodating therewithin link 56, which, by its upper end is pivotedupon -pin"57 mounted upon plate 49 and extending inwardly of recess 55--adjacent theupper end of the latter. a f e Each of saidlower sleeves46, ad'acent-its lower end; is provided with'a rigidly affixed pin 58,which extends toward the-lower window'sash, ina transverse :relationwithand past said plate 49; z v

Coacting with each side edge-ofthe lower windowsash is 59-, which byitsflower end'is. pivoted to the outer faceof-plate 49, substantiallycentral-ly'thereof, 'by means of pin '60. By itsupperend-said arm-59 is.p ivoted'itmthe lower end of: the' uppersleeve 47; upon pin 61.

When the lowerwindow sash remains within the window opening or when thesame is anguilarly Shiftfid,;jl1 either ofthose-cases pinr5firemainswithin the .closed: end of recessv or :sloti4, pins. :58: constituting.the supporting pivot or fulcrum for the sashm'hile in thosepositions,;;as seeninFigs. 4 andlSr. Whentherlower-window sash has been;shifted to. the horizontalposition, as seen Big; 4,.lowerzcnds of uppersleevessdfl coming in contact'wtith the upper: ends oflowersleeves-AG,prevent further downward shifting movement of the lower windowsash bew nane- .WheirieMvs sash is shifted angularly from horizontal; tgwalfdfithe window opening, then arms 59 shift the upper sleeves 47 away fromthe lower sleeves 46, as is seen in Fig. 8. When the lower window sashis within the window opening in closed position, arms 59 remain in avertical position and in parallelism with inner rods 35, sleeves 46 and47, and vertical sash bars 24. Similarly as was already described inconnection with the upper window sash, when the lower window sash isbrought to its horizontal shifted position, shown in Fig. 4, the outerface of the window pane 25 will be exposed within the dwellingpermitting access thereto for the purpose of washing or cleaning. Thelower window sash is capable of assuming various angular positions fromvertical closed position to the horizontal position, as is seen in Figs.4 and 8. No matter what particular angular position, from the verticalclosed position, the lower window sash assumes, it is capable of bodilyshifting in a vertical direction as is clearly indicated in Figs. 4 and8, being guided in its bodily vertical shifting movement by the innerpair of rods 35 and sleeves 46 and 47.

Arms 59 support the lower window sash in its angular adjusted position.

It is also noted that when the lower window sash is in a horizontalposition pin 58 does not extend to the closed end of recess 54, butremains substantially centrally thereof, as is seen in Fig. 4. It isalso noted that when the lower window sash is in a closed positionwithin the window opening, the same is pushed in the direction away fromthe dwelling, until said lower window sash is on a common plane with theupper window sash, with the lower horizontal sash bar 26 of the upperwindow sash interconnected with the upper horizontal sash bar 23 of thelower window sash, through joint 30, as is seen in Fig. 2. In thatclosed position of the lower window sash pins 58 will find themselveswithin the closed ends of slots 54, as is seen on reference to theshowing in Fig. 8. In that closed position of the lower window sashWithin the window opening arms 59 will not be on a vertical line, buttheir lower ends will be on a plane toward the outside of the dwelling,with the upper ends of said arms 59' on a plane nearer to the dwelling,position substantially opposite from that shown in Fig. 7.

To bodily shift the lower window sash to the plane away from that of theupper window sash, first the upper end of the lower window sash isshifted within the dwelling, for bringing the lower window sash to anangular position. Thereupon the lower window sash while inthat angularposition is bodily shifted in an upward direc tion until the lowerhorizontal sash bar 22 clears sill 14. When this has been accomplishedthe lower end of the lower sash is shifted inwardly of the dwelling.This latter operation causes link 56 to angularly shift and assume theposition out of recess 55, as is seen in Fig. 7. Bodily shifting of thelower portion of the lower window sash moves the lower end of the lowerwindow sash away from pins 58 so that said pins 58 remain out of slots54, as is seen in Fig. 7.

When the above several steps have. taken place the lower window sashwill be moved out of the plane of the upper window sash, with the lowerwindow sash bodily shifted within the dwelling, as is seen in Fig. 7,ready to be shifted in an upward direction to assume an alined positionon a horizontal plane with the upper window sash, thereby completelyclearing the lower portion of the window opening.

Obviously, arms 59 must shift in the upright direction when the lowerwindow sash is bodily shifted upon the plane removed from the plane ofthe upper window sash.

Were the molding strip plates 32 rigid with the vertical sash bars 28 ofthe upper window sash, arms 59 while shifting in an upward directionwould encounter said molding strip plates 32 coacting with the upperwindow sash. To obviate the obstacle suitable mechanism is provided forcausing said molding strip plates 32 at the upper window sash to shiftaway from the vertical frame side members 11, thereby providingclearance between extensions 21 and lips 33 for said arms 59 to shiftthere-; between in their upward shifting movement.

The lower corner portions of said lips 33 are filed away as at 62 forpermitting entrance of said arms 59 past said lips 33 and extensions 21,at the inception of the upward shifting movement of said arms 53 as theyare brought oppositely of the ends of the lower horizontal sash bar 26of the upper window sash. This contact of arms 59 with the filedaway'portions 62 .of lips 33 will cause molding strip plates 32 at theupper window sash to bodily shift away from the vertical frame sidemembers 11, 'or more specifically from their contactual engagement withextensions 21. The mechanism for bodily shifting molding strip plates 32and lips 33 away from weather strips 20 and extension 21, includestransverse slots 63 one adjacent each end of the portion of the moldingstrip plate 32 which remains in the immediate contact with the innerface of each vertical sash bar 28 of the upper window sash.

Washer 64 overlies the body portion of the molding strip plate 32 whichis in contact with the inner face of each vertical sash bar 28,including the slot 63. Screw 65 is passed through washer 64 and isdriven into the vertical sash bar 28. By virtue of this constructionscrews 65 constitute guides upon which each molding strip plate 32 iscapable of bodily shifting to or away from vertical frame side members11. For normally maintaining the molding strip plates 32 shifted towardthe vertical frame side members 11 with lips 33 normally in a contactualengagement with extensions 21, a pair of resilient wires 66 is provided,one adjacent each end of the portion of each molding strip plate 32which contacts with the inner face of the vertical sash bar 28. One endof each wire 66 is driven into the vertical sash bar 28, or is otherwiserigidly aifixed thereto, as at 67. The opposite end of each wire 66 issoldered or otherwise afiixed to the underface of the portion of eachmolding strip plate 32 which overlies the vertical sash bar 28, as at68. Normally said wires 66 due to their inherent resilient nature, tendto urge said molding strip plates 32 and their lips 33 toward thevertical frame side members 11 with lips 33 in contactual relation withextensions .21, as best seen in Fig. 6. When however under the actuationof arms 59 as the latter pass past the filed away corners 62 of saidlips 33, the latter as well as the molding strip plates 32 are caused toshift away from the vertical frame side members 11 and against thetensioning action of wires 66, thereby shifting said lips 33 away fromtheir contactual relation with extensions 21 effecting a slot betweensaid lips 33 and extensions 21 of a width suificient for said arms toenter and thereby to permit the unobstructed upright shifting movementof said arms 59 as the lower window sash is bodily shifted upon theplane removed from the plane of the upper window sash.

To accommodate said wires '66 the body portions of said vertical sashbars 28 are scooped or hollowedas at 69. In Fig. 1 portions of saidmolding strip plates 32 are broken away to illustrate depressions 69,wires 66 and the connections of the latter with the vertical sash bars28 and said molding strip plates 32.

When the lower window sash has been moved in a downward direction andaway from its alinement on a horizontal plane with the upper windowsash, and once said arms 59 have cleared lips 33, the molding stripplates 32, by virtue of the action of wires 66, assume their normalclosed position, shifted toward the vertical frame side members 11, withlips 33 in a reestablished contactual closed relation with extensions 21as seen in Fig. 6.

From the hereinabove description it will be apparent that when the lowerwindow sash remains in a horizontal position the upper window sash maybe shifted downwardly and oppositely to the lower portion of the windowopening, and as far as arms 59 will permit. Thus, either 7 sir-w ndowsashes when in ahorizontal position may ez'shi tedi re rhe d rec nto a pd e m ne position in order to have :a convenient 'accessto wash-t eouter Eachspringflt) is disposedintermediately of rods 35 and.

located-within each housing 34. The upper end of each spring 70 isattired to the upper horizontal frame member 13., :as at :Each spring 71 is located forwardly of each inner rod 35,,within-each housing 34, andsubstantially intermediately ofeach inner rod and each molding strip 19.The

upper end of each spring 71 is ailixed to the upper horizontal framemember 13.

Rigidlyaflixed to each upper sleeve 39 is bar 73, and rigidly affixedto, each of said upper sleeves 47 -is bar 74'. Said bars 721' and 74. bytheir opposite lower ends are at timesxin :a frictional contract withthe lower sleeves 38 I and; 46, respectively, irrespective as to whetheror not uppersleeves39 :and 47 are in contact by their lower ends withthe :upper ends ofthe lower sleeves 38 and 46, respectively, as seenin'Fi-g'. 4, or whether said upper sleeves are inuazspaced relation fromsaid lower sleeves,as is seen inFig. 5-. ESaidbars73, and 74 are of aresilient nature for the purposeof exerting a comparatively strongfrictional: contact upon said lowertsleeves' 38 and 46, respectively,and consequently for the purpose of engenderizng-rfriction between saidsleeves 38 and the outer pair of r:cxis 35 as well .as between saidsleeves 46 and the inner nodsSS.

integrally formedwith :and laterally projecting from each bar. 73 and74. are lugs 73 and 74, respectively, to whiohthe lower ends of. springs70 and 71, respectively, are affixed.

By virtue of the friction aforesaid there is a bra-king action betweensleeves 38 :and 46 and their respective outer :and ,inner'mds 35. Thisbraking action prevents window sashes from shifting in the upwarddirection unlessmanual pressure is imparted to the sashes in ordertonovercome the said friction and the braking action between :the saidlower sleeves and rods 35.

lnlieu of springs 70 and T71 usual cords may be a-iiixed to. lugs and.74; to be actuated by the conventional weights Whether springs or cordsare used, in either event the braking action between the lower sleevesand:

their coacting rods willbe maintained for the purpose hereinabovespecified. I

Latching devices 75. (Fig. l) are .aflixed to the upper horizontal sashbar 23 and the lower horizontal sash bar 26, of the lower and upperwindow sashes, respectively, whereby the two sashes may be locked whenthe same remain in .a-.closed'positionwithin the window opening, as isseen in Fig. 2.

Ring 76 may be affixed to the upper horizontal sash'bar 2-3 of the lowersash whereby said sash may be manually pulled from its closed positionshown in Fig. 2 for angularly' shifting the same.

Carried by the lower ends of molding strip plates 32 is a pair ofspacers 77, best shown in Figs. 1 and 2, which preventcontact ofthelower window sash with the upper window sash when the lower window sashhas been brought out of the plane of the upper window sash when the sameis upwardly shifted, as is seen in Fig; 7', thereby preventing marringofthe two window sashes which would ensue if the sashes were in :africtional contact.

it is also noted that when the lower windowv sash is in a closedposition within the window opening, and in aline-v ment 'ona verticalplane-with thesupper windowposition best shown in Fig. 2,, extension53;, with platesandjSl, will remaininanz-outwardly shiftedpositionvvvgnh" relation to thedwelling, thereby causing Pil :8 towithinthe closed end ofrecess 541as is seen'in .Fig fii;

Thus, said bars 73 and 74' have av double function, namely,they counteract the action of springs ,and- 71 .to. maintain the sashesin their vertical adjusted position within the window, and secondly,they maintain. the win dow sashes in. their angularlyadjusted-position-within thewi-ndow, other than the horizontal.position, because in that latter position the sashes are maintained byvirtueof the upper sleeves having come in contact with, the lQWersleeves.
